This is what truck drivers refer to as a Mexican convoy….You usually see a whole string of trucks,cars,& commercial vehicles headed to Laredo Tx,El Paso Tx,& just about any border crossing where they sell these rolling wrecks to brokers who carry them across the border & resell them in Mexico. Home built towbars & jerry rigged fuel systems.The police know not to stop them because no one speaks english & will just disappear if given a citation.
